Description The Great Proterozoic Fold Belt of India (GIPFOB) is the inferred accretion zone between the North India Block (NIB) and the South India Block (SIB). Mesoscopic structures, phase petrology, and U-Th-Pb (total) monazite ages in the Bangriposi Shear Zone (BSZ) located in the eastern syntaxis of the GIPFOB along the fringe of the Paleo/Mesoarchean Singhbhum Craton (SC) are examined to constrain the time of NIB-SIB assembly. The BSZ at the eastern fringe of the Archean Singhbhum Craton is a NNE-trending west-vergent 0.95-1.0 Ga greenschist-facies (
